The Secrets of Cornwall by Mark Thomas.

This video fuelled my interest in a more detailed search for the hidden buildings and ducts that make up the Internet Backbone of the UK.

Watched this video several hundred times pausing and following Mark’s journey mapping the sites he visited. Also used a number of sources like Secret Bases and Internet Maps to map other interesting sites. Some sites were found by endlessly and painfully zooming and scrolling Google Maps !

I have made up several KML files locating each these sites and the route of the GTN and other fibre cables.
